bios replacement

[Shiori]

i dunno much about mobos, so i thought i'd ask for help here.

i have a VERY old socket 5 mobo with an amd 100mHz cpu that my sister wanted to use in her room for a word processing machine. unfortunately, it has a very outdated 1994 American Megatrends bios, which doesn't detect the CDROM drive. i was wondering if i can replace this AMI bios, and if i can, what type/kind of bios do i replace it with?

thanks for any help.
